Abstract
The utility model relates to an armrest overturning mechanism for a train seat. The armrest overturning mechanism mostly comprises an armrest body and is characterized in that the armrest body is connected with a rotary shaft sleeved by a limiting device. In use, the limiting device is arranged in an arc groove of the armrest body. By an elastic force of a gasket, the limiting device is made up of the gasket and a friction piece. The armrest overturning mechanism has following beneficial effects: resistance and service lifetime are determined by the number of the gasket and the friction piece and height difference therebetween, thereby providing a limiting sense when the armrest body of the seat is folded and expanded; and by means of the structure of the simple armrest body, more space of the seat is released and universality of disassembly and assembly is enhanced.
Description
Technical field
The utility model relates to the technical field of train seat, and specifically the handrail switching mechanism on a kind of train seat, relates in particular to the inhibiting device on switching mechanism.
Background technology
At present, the function of train seat is tending towards variation, the turning handrail of packing up is set on train seat, can provide a platform that can support for passenger, for the place that offers arm have a rest when taking for a long time, armrest has improved traveling comfort in train and the whole class of upholstery greatly.
But, the existing train seat handrail overwhelming majority is packed up and expansion is there is no spacing sense at it, handrail is under collapsed state like this, when train shakes or jolts in operational process, armrest there will be the phenomenon that teeters or shake, and also makes the article on armrest move thereupon, simultaneously the armrest edge surface cover of seat that also can rub, above-mentioned these phenomenons do not get a desired effect, and have influence on the contrary passenger's normal use.
For the defect in prior art, need a kind of spacing sense strong and spacing stable, also to be convenient to the Novel armrest inhibiting device of adjusting simultaneously, also to guarantee the intensity of use and the fatigue life of upset simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of improved train seat handrail switching mechanism, it can overcome the armrest body overwhelming majority in prior art does not have spacing sense when it is packed up and launches, when train shakes or jolts in operational process, armrest there will be the some shortcomings of the phenomenon that teeters or shake.
To achieve these goals, the technical solution of the utility model is: train seat handrail switching mechanism, it mainly comprises armrest body, it is characterized in that: described armrest body rotating shaft is connected, and is arranged with inhibiting device in rotating shaft.
During use, inhibiting device is arranged in the arc groove of armrest body, by the elastic acting force of packing ring, described inhibiting device is comprised of packing ring and friction member, the quantity of packing ring and friction member and diff-H determine drag size and service life jointly, make the limited location sense when packing up and launch of armrest body, utilize easy armrest body structure, release seat spaces that can be larger, can improve the commonality removing and installing simultaneously.
Accompanying drawing explanation
Fig. 1 is the dispersed texture schematic diagram of the utility model one embodiment.
Fig. 2 is the dispersed texture schematic diagram of the another embodiment of the utility model.
The specific embodiment:
Below in conjunction with drawings and Examples, the utility model will be further described.
Mark in each accompanying drawing is expressed as follows: 1 end cap, 2 friction members, 3 packing rings, 4 rotating shafts, 5 axle sleeves, 6 bolts, 7 armrest bodies.
Train seat handrail switching mechanism described in the utility model, it mainly comprises armrest body, it is characterized in that: described armrest body rotating shaft is connected, and is arranged with inhibiting device in rotating shaft.Described inhibiting device consists of packing ring, friction member and end cap, and described packing ring adopts elastic component wave mode packing ring.Between armrest body and rotating shaft, by axle sleeve, be connected, between axle sleeve and rotating shaft, for being rotatably connected, described armrest body is provided with arc groove, and one end of rotating shaft is arranged in arc groove.End cap is rounded, and the middle part of end cap is provided with circular port, and the end of rotating shaft is set in circular port and is connected with end cap, and end cap is provided with 2 screws, and friction member is provided with the spacing hole corresponding with screw, and screw is provided with adjusting bolt.Armrest body spins upside down in the fan section of rotating shaft, rotating shaft itself is to be fixed on the skeleton of seat, rotating shaft is provided with elastic component wave mode packing ring, on wave mode packing ring, it is friction member, outside is end cap again, axial resistance and the elastic force of handrail are all fixed by end cap, make handrail form independent assembly simultaneously and carry out assembly and adjustment.
In enforcement, as Fig. 1, shown in 2, the spacing armrest body by arc groove of armrest and the rotating shaft of the present embodiment realize, with axle sleeve, assemble between the two, described rotating shaft is fixed on cushion frame, between rotating shaft and axle sleeve, it is relative motion, friction member contacts with rotating shaft and relative motion, on friction member, dome contacts rear and exerts pressure with rotating shaft, produce spacing, therefore for uniform pressure, wave mode packing ring plays corrective action, when armrest rotates around rotating shaft, described relative motion only has axle sleeve bottom surface and the friction of rotating shaft bottom surface, rotating shaft is not moved, rotating shaft end face and the relative motion of friction shoe end face, rotating shaft is simultaneously fixed by friction member and axle sleeve both ends of the surface, described friction member is different from axle sleeve both ends of the surface area, while applying same pressure, the friction force of axle sleeve is greater than friction member, while therefore working, the abrasion loss of friction member can be little, the pressure of friction member is from end cap, the pressure of end cap applies with wave mode packing ring and has formed a closed control volume, when the spacing sense of armrest need to be adjusted, only need the degree of tightness of adjusting bolt.In order better to control use state, can adjust the torque magnitude of bolt, with torque-indicating wrench adjustment, fix.
